Powermax 155 replacement

[darren bastin]

Hi, I am quoting to replace a powermax for a vaillant 428 and megaflo and it comes out a bit pricey. A combi however big will not do. Does anyone have any suggestions for an alternative system, the main criteria is plenty of hot water to multiple outlets. Your suggestions would be appreciated.

Viesmann 222 though they aren't cheap either.

Thanks for replying , is the viessman 222 a similar product to the Valliant 937 ie a combi with a small store , or is it a combined boiler and thermal store with mains cold and a blending valve, how does it work and what sort of water delivery ?

Its a combined boiler and unvented cylinder 100l (?)

I've replaced a Worcester highflow 440 with a Viessman 222 and it work well. Also easy to install. Speak to both Viessmann and Vaillant technical help desk and they'll give you all the info you require with the new install.
